1 Claim. (Cl. 120-410) The present invention relates to new and useful improvements in furnaces and has for its primary objectto provide, in a manner as here-- inafter set forth, a device of this character in the nature of a self contained unit which is adapted to be expeditiously installed for operation, either permanently or temporarily, in a fire place.

. Another very important object of the invention is-to provide a furnace of the aforementioned character comprising a novel construction and arrangement whereby a continuous circulation .of filtered and forced heated air may be had.

Other objects of the invention are to provide a furnace of the character described which will be comparatively simple in construction, strong. durable, highl etliclent and reliable in operation, compact, attractive in appearance, safe and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become ap- Figure 4 is a vertical sectional view, taken substantiaily on the line 4-4 of Figure 1.

Figure is a cross sectional view, taken substantially on the line 55 of Figure 3. Referring now to the drawings in detail, it wil be seen that the embodiment of the invention which has' been illustrated comprises a cabinet which is designated generally by the reference numeral I, said cabinet being of any suitable'material. As illustrated to advantage in Figs. 1 and 2 of the drawings, the cabinet I is a shape and dimensions to fit into a fire place 2. Metallic runners or skids I are provided beneath the bottom:

4 of the cabinet I to facilitate placing the furnace in the fireplace 2 or removing said furnace therefrom.

Mounted at an intermediate point in the cabinet I is a vertical partition 5 the lower end of which is spaced above the bottom 4 of said cabinet. Extending from the lower end of the partition 5 to the front 8 of the cabinet'i is a horizontal partition I. The partitions I and 1 procold air chamber I and an air intake passage or tunnel 2 communicating with said chamber 8. The partitions 8 and I further define an air heating chamber or compartment I0 in the front portion of the cabinet I. A

Air enters the intake 9 through. ascreened 1 opening 'II 'in-the lower portion of the front 6.

"Mounted in the intake 0 is a filter l2 through which the ingoing air must pass. Thechamber ll communicates with the chamber 8 for receiving air therefrom through a circular, flanged opening If in the partition 8.

An electric motor I4 is mounted on a suitable support It in the chamber I. The electric motor I4 drives a fan or blower I6 of suitable :type which is operable in the opening II, said blower .forcing the air from the chamber 8 into the chamber I 0. The upper portion of the fronti of the cabinet I is provided with a grilled or barred hot air discharge opening I'l. Another discharge 'opening I! is provided in a lower portion ofthe front i, said opening I8 being provided with a hinged grill l9.

Mounted in the chamber I0 and spaced from the walls thereof is a combustion chamber which is designated generally by the reference numeral 2.. The combustion chamber includes a housing 2| to the interior of which access is had through a hinged, windowed door 22, said door 22 being leak-proof when closed and aligned with the opening it.

The housing 2| is provided with a lateral extension 23 (see Figs. 3 and 5)- which projects to the adjacent side wall of the cabinet I and which communicates with an air intake opening 24 in said cabinet. Mounted in the lower portion of the housing 2| is a gas burner 25. The pipe 26 of the burner projects through aside wall of thecabinet I and has connected thereto a suitable conduit 21 from'a suitable source of gas. A control 2| is provided for the pilot light 29 of the burner 28 and a control 80 is provided for the regulating valve 3| of said burner. It will be observed that the controls 28 and 30 are manually operable from the front of the cabinet I.

, Incidentally, the reference numeral 32 designates a suitable control which is located on an upper corner portion of the cabinet'from 6 for the electric motor I4.

Mounted in the housing 2| above the burner 2! is a plurality of radiants 33. Above the radiants 33 a plurality'of oppositely inclined, stag-' gered baflles 34 is provided in the combustion housing 2|. A flue 3i rises from the housing 2| vide in the cabinet I what may be referred to as a and passes through the top 30 of the cabinet I,

the foregoing. With the electric motor It in operation, the blower It draws air into the chamber 8 through the intake 9. In passing through the iilter [2 this air is thoroughly cleaned. From the chamber 8 the blower It forces the air through the opening it into the chamber it where it circulates around the combustion unit 20 and, of course, is heated thereby. This heated air then passes out through the openings i1 and II and circulates'throuflh the building. The electric motor H is automatically controlled or regulated through the medium of the thermal control 32 which may be manually adjusted as desired. Also, if desired, the burner and pilot controls may be automatically actuated. As suggested in dotted lines in Fig. 4 of the drawings, access to the interior of the housing 2! may be conveniently had by simply swinging the grill l9 and the door 22 downwardly to open position. If desired, the apparatus, with the burner 26 out of operation, may be used in warm weather, for example, for removing dust, pollen, etc., from the air and circulating the filtered air through the house or building.

It is believed that the many advantages of a furnace constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:.

A furnace comprising a cabinet including a front wall having air intake and discharge openings therein and a side wall having a draft opening therein, a vertical partition in the cabinet separating the same into a front heating chamber and a rear air chamber. said heating chamber having a bottom spaced above the bottom of the cabinet to provide an air intake passage communicating with said air intake opening in the front wall, a casing mounted in the heating chamber in spaced relation to the walls thereof and forming a combustion chamber, said combustion chamber comprising a lateral extension to said side wall of the cabinet and communicating with the draft opening therein, a burner, including a pilot light and control valve mounted in the combustion chamber. the extension ac-. commodating said pilot and control valve, said partition having an opening therein behind the central portion of the casing, and a fan positioned in said last-named opening for blowing air from the rear air chamber into the heating chamber and around all of the sides of said last-named chamber.
